Psychology 101: Investor Panic! ... Time to Buy?

The U.S. stock markets have dropped 4% this week, and investors' fear levels are near the yearly highs set in March. Investor psychology is a funny thing -- but it's predictable -- and understanding it can make you a lot of money.

We've been mentioning in our blog posts over the past 2 months that as the stock market has gone higher, investors have grown more and more nervous. They have felt inclined to sell to "cut their winners short" just to lock in their gains so far. A brief market sell-off is exactly what drives investors to feel afraid when they've already made so much money.

Let me offer myself as an example. Every 6 months I create a 10 stock portfolio using a basic Yahoo! stock screener and a little due diligence (calling company CFOs, reading SEC filings, etc...). Takes me about 8 hours to complete the whole process, and the average return has easily been over 20% annually. Here are some of the older portfolios (which I stopped posting after 2005 due to time constraints). This January's portfolio is already up 25%. Which is obviously better than anticipated.

Frankly, that 25% 8-month return scares me. My account is 25% larger in only 8-months. Wow, it feels good. However, like almost everyone else, I want to take that money off the table so I don't lose it. I'm susceptible to cutting winners short. Why don't I? Because I know that my nervousness is not a trading plan, it's a road to underperformance.

Using our Marketpsych sentiment analysis tools, we've been watching the pain level rise over the past week. See this Marketwatch article (which mentions our Investor Pain Index) for a few details. The chart below was generated using our real-time proprietary sentiment software and it is plotted against the QQQQ (Nasdaq 100 ETF):
This chart shows the relative amount of pain measured among investors.

As you can probably see in the chart, the last time pain was so high was a great time to invest. So consider using stomach-churning pain as a Buy indicator. You don't need to "catch the falling knife," but you may want to enter buy stops slightly above the market, because any "relief rally' will be fast and furious.

Personally, I think the pain will probably spike again (and the market will sell-off), in a second wave, before a real buying opportunity presents itself (August and Spetember are yet to come). Consider investing some idle cash during an August sell-off, although also consider somewhere safer than the US dollar (e.g. Singapore or Malaysia) when those markets get hit.

Best wishes,
Richard

A Bull in the China Shop: The Fundamentals of the Worldwide Share Rally

We're in the midst of the biggest bull market in history. Virtually every asset class has been yielding double-digit percentage gains annually. Here in the United States, the boom is less obvious. In Asia, it is unmistakable and profound. Since this is a blog post, not a book on economic history, I'll try to keep my commentary on this world-changing transformation brief. In particular, we'll go back to the subject of China, which I think will be the defining story of the next century.

Pundits cite numerous reasons for the boom, the foremost of which is a liquidity glut. One explanation for the "easy money" says that as Asian and Middle Eastern nations receive US dollar payments for their trade with the United States, and they have enormous trade surpluses ($1 trillion in China's reserves so far), they are inclined to re-invest that money in dollar-denominated assets to avoid driving up the value of their own currencies. This buying pressure on T-bonds and T-bills leads to decreased interest rates and easier credit for business expansion worldwide.

The general idea is that lower interest rates make borrowing cheap. And who wouldn't borrow at 6% in order to invest in a business with a cashflow over 16%? That's a low-risk return of over 10% annually. Now multiply it times 4 using leverage (40% return), and you have a high-risk hedge fund or private equity fund at your finger-tips.

China alone is growing 10% per year. Many of its businesses are growing earnings 20-30% annually for the past 5 years, as evidenced in the China Stock Directory. Yet the Yuan is pretty stable versus the US dollar, so currency risk is low. Private equity funds can make a killing by arbitraging this type of interest rates to earnings differential. Makes sense that the Chinese government is a pre-IPO investor in Blackstone -- Blackstone gets preferred access to fast-growing Chinese companies, and China gets the know-how to set up a domestic private equity industry.

So there is a fundamental logic to the boom - that's my point anyway. But since this is an investor psychology blog, how can we know when bubbles form on top of booms? In particular, is China in a bubble? Some say that a PE of 42 for China Communications Bank is high, especially when HSBC has a PE of 13. Does a high PE alone mark the top of a bubble? Greenspan used the high PE = bubble logic when he insinuated the US market was irrationally exuberant in December 1996. His timing was way off, but it does have a historical logic.

In my studies of sentiment, tops are usually marked by high optimism. But so are the rallies on the way to the top. If you shorted every period of 2 standard deviations above average optimism over the last 20 years, you'd have zero returns. No matter how pessimistic you are, you have to admit that shorting optimism does not work without other objective criteria to go by.

In April, 5 million new stock brokerage accounts were opened in China. That is 2/3 more than were opened in all of 2006 (per the Economist magazine). That sounds like an investor frenzy. But guess what - they shoud be excited. China has been booming for 20 years, and the tipping point has finally been reached where domestic Chinese investors can chase hot stocks. It's healthy that people are getting involved. Does that mean they will emerge unscathed? No.

When will the psychology of the Chinese bubble become a problem? As I mentioned in a previous blog post, probably not until next year. So far the share prices have been rallying less than two years. While PE's are high in big name stocks, there are still some bargains in China(granted, many with murky accounting).

Even after last year's rally in the US (modest as it was), my stock screens found more cheap small-cap stocks this December than at any time in the past 3 years. And they are up 30+% since then. A rally does not prove a bubble, but it is necessary to one.

So the Asian economic boom is finally being followed by a real stock market boom (China and Vietnam in particular). This is good news, as it means their financial systems are globalizing. The selloff of May 2006 indicated that while some investors were skittish about the huge recent gains, the general trend remains extremely positive. This year is no different from 2006 in terms of economic growth in Asia, except that investors are finally catching on and assets are at or exceeding their fair values worldwide. Yet, they can certainly go further. There will be scary selloffs along the way (probably very steep), but they will be clearing the air for the next rally. Those are my thoughts at the moment. They may change at any time, as flexibility is the paramount virtue in the markets.

Next post we'll look at some recent neurofinance studies.
